The dizzy heights of Everest are to be attempted by a hardy group of Stokesley students tomorrow.

But the nine 16 and 17-year-olds from Stokesley Sixth Form College are not travelling to the Himalayas. They are attempting to conquer the equivalent of Everest by climbing Roseberry Topping 16 times in a day.

The sponsored challenge is to raise cash for Macmillan Cancer Relief.

Ed Cutler, challenge organiser and one of the climbers, said: "So many people close to our group have been affected by cancer, and have had superb support from Macmillan, that we wanted to give something back.

"The challenge isn't going to be easy - we have to complete the climbs in just one day. But we have been training very hard for the last two months."

Everest, on the Nepal-Tibet border, is the highest mountain in the world at 8,850m (29,035 feet).

Roseberry Topping is 322 metres high (1,056 feet) and the climbers are counting both up and down treks as part of their attempt.
